3 Claims.

This invention relates to improvements in doorfastening means.

The principal objects of the invention are directed to the provision ofmeans for fastening 5 a pair of swinging doors in closed relation.

' In connection with garages or the like it is customary to apply a pairof swinging doors which are relatively large and heavy and difficulty isexperienced in holding them in closed relation.

l' According to this invention I provide a novel means for securing sucha pair of doors in closed relation which operates prociently for thelocking of the doors one to the other and door frame which is simple inform and easy to operate.

l Various changes and modifications may be made in the form of theinvention without departing from the spirit and scope thereof and thenovel features and advantages thereof will be hereinafter observed fromthe following description of the preferred form of .the invention withreference to the drawing wherein:

Fig. 1 is an elevational view of a pair of swinging doors having thelocking mechanism of the invention associated therewith;

Figs. 2 and 3 are sectional plan views on the line 2-2 and 3 3respectively of Fig. l;

Fig. 4 is an elevational sectional view on the line 4--4 of Fig. 1; and

Fig. 5 is a sectional plan view on the line 5-5 of Fig. 1.

Referring now to the drawing in detail, the invention will be more fullydescribed.

In the drawing 2, 4 and 6 represent frame members around a door opening.Stops 8, l0' and l2 3;, are for a pair of doors D and D to abut againstwhen in closed relation as shown. There are hinges i4 to facilitateswinging of the doors. An`

operating handle l 6 on the outer side of the door D carries a lever I8which is pivoted at 20 to a vertically slidable bar 22.

There is a handle 24 inside the door to facilitate the manipulating ofthe lock mechanism from the inside. Guide members 26 are provided forthe bar 22 to facilitate the up and down sliding movements thereof.Transverse locking members 28 are provided which are pivoted to doors Dat 30 and their ends are so arranged as to engage behind brackets 32bearing the door D.

An extending portion 36 of the upper member 28 is pivoted at 38 to thelower end of a bar 40 which is slidable vertically in a guide 42associated with door D.

Upper and lower plates 44 and 46 are secured to the upper frame 4 and alower sill 48, which plates are slotted to receive the ends of barmembers 22 and 40.

The parts are shown in Fig. 1 in a locked position and to unlock thedoors it is necessary to rotate operating member i6 counterclockwise. 5This motion throws bar 22 upwardly and pulls bar 40 downwardlyconcurrently. As this occurs the ends of bars 22 and 4U are withdrawnfrom the recesses of plates 44 and 48, and the outer ends of members 28are moved upwardly and be- 10 yond the'end of members 32. -The doorsthereby are now ready to be swung outwardly to an open position.

It will be observed that the mechanism is constructed and arranged insuch a way that the 15 doors D and D are not only locked together butare locked to the frame and sill adjacent to the doors. The mechanismlocks the doors, securing them against opening in such a way that theyare held against warping which is a very com- 20 mon occurrence.

A bar member 5U is associated with the operating lever I6 on the door D.This member is provided with an opening 52 and rests adjacent to asimilar bar member 54 secured to door D'. 25 Bar member 54 is alsoprovided with an opening 5B so that openings 52 and 54 are adjacent eachother locked with a padlock or the like in a locked position, when intheir closed relation.

While I have described the invention in great 30 detail and with respectto a preferred form thereof, it is not desired to be limited theretosince many changes and modifications may be made therein withoutdeparting from the spirit and scope of the invention. Wh-at it isdesired to claim and secure by Letters Patent of the United States is:

1. The combination with a frame having a door opening and a door hingedthereto at its outer edge for swinging between open and closed 4positions of a means for securing said door in said closed positioncomprising, an operating member pivoted to the door, a lower bar memberslidable vertically relative to the door and having its lower endnormally in engagement with 45 a lower part of said frame, a pivotalconnection between said operating member and said lower bar member, anupper bar member slidable vertically relative to said door and havingits upper end normally in eng-agement with the up- 50 per part of saidframe, a single link member having a transverse part pivoted to saidlower bar member and a curved part pivoted at its upper end to the lowerend portion of s-aid upper bar member, and a pivotal connection between55 an intermediate portion of the link member and the door, all adaptedand arranged whereby movement of said operating member on its pivotcauses upward movement of said lower bar member and actuates said linkmember to move said upper bar member downwardly.

2. The combination with a frame having a door opening and a pair ofdoors hinged thereto for swinging between an open and a normally closedposition of a means for securing said doors in said normal positioncomprising, an operating member pivoted to one of said doors and havinga lever part normally overlying the other door, a lower bar memberslidable vertically relative to said one door and having its lower endnormally in engagement with a lower part of said frame, a pivotalconnection between said operating member and said lower bar member, anupper bar member slidable vertically relative to said one door andhaving its upper end normally in engagement with an upper part of saidframe, and -a single curved link member having one end portion normallyin engagement with said other door and a part intermediate its endspivoted to said door and its other end portion pivoted to the lower endportion of said upper bar member, all adapted and arranged wherebymovement 'of said operating member on its pivot causes said lower barmember and said lever part to move from their said normal positions soas to Vactuate said curved link member and move said upper bar memberdownwardly from its said normal position.

3. The combination with a frame having a door opening and a door hingedthereto at its outer edge for swinging between an open and a normallyclosed position of a means for securing said door in said normalposition comprising, an operating member pivoted to the door, a lowerbar member slidable vertically relative to the door and having its lowerend normally in engagement with a lower part of said frame, a pivotalconnection between said operating member and said lower bar member, anupper bar'member slid-able vertically relative to said door and havingits upper end normally in engagement with the upper part of said frame,the lower end portion of said upper bar member curving outwardly towardssaid outer edge of the door, a single link member having a transversepart pivoted to said lower bar member and a curved part pivoted at itsupper end to said curved Vend portion of the upper bar member, and apivotal connection between an intermediate portion of the link memberand the door, all adapted, and arranged whereby movement of said operat-JULIO REIS.
